[PATCH 3/3] drm/i915: Return correct size for rotated views

[Tvrtko Ursulin]

From: Tvrtko Ursulin <tvrtko.ursulin@intel.com>

Currently object size is returned for the rotated VMA size which can be
bigger than the rotated view itself. Since the binding code pads all
excess size with scratch pages the only minor issue with this is wasting
some GGTT space, but still feels nicer to fix and report the real size.

Time to change that variable name. pages is already used in both the vma
and obj to represent the struct sg_table, not the count.

Changed to "size_t size" as per IRC discussion and resent the series. 
Thought that will be cleaner since two of of three patches are now v2.
